YIHENG B-SUN Series Benchtop Xenon Arc Weathering Test Chamber

Overview

The YIHENG B-SUN Series Benchtop Xenon Arc Weathering Test Chamber is an engineered solution for accelerated weathering evaluation of materials under controlled, reproducible solar-spectrum simulation. Utilizing a high-intensity xenon arc lamp as its radiation source, the chamber replicates the full UV–visible–near-IR spectrum (290–800 nm) of natural sunlight—enabling correlation with real-world outdoor exposure per internationally recognized test standards. Unlike fluorescent UV or metal halide systems, xenon arc technology provides spectral fidelity critical for evaluating photodegradation mechanisms in polymers, coatings, textiles, automotive components, and packaging materials. The benchtop form factor delivers laboratory-grade weathering capability without requiring floor-standing infrastructure, making it ideal for QC labs, R&D centers, and contract testing facilities with space constraints.

Key Features

• High-fidelity xenon arc illumination system compliant with ISO 4892-2, ASTM G155, and SAE J2412—ensuring traceable spectral output and irradiance stability.
• Optimized optical design featuring a precision-machined reflective mirror array to maximize irradiance uniformity across the sample plane (±10% deviation over 150 × 150 mm exposure area).
• Motorized sliding sample tray with rail-guided extension—accommodates standard petri dishes, vials, cuvettes, and custom fixtures; supports simultaneous multi-sample exposure with independent positioning.
• Interchangeable lamp compatibility with OEM-grade North American xenon lamps (e.g., Ushio XBO 2500W/3500W); rated lamp life ≥1,500 hours at nominal power, minimizing operational downtime and recalibration frequency.
• Industrial-grade 9.7-inch capacitive touchscreen HMI powered by a certified PLC controller—providing intuitive menu navigation, real-time parameter visualization (irradiance, black panel temperature, humidity, spray cycle), and automated fault diagnostics.
• Integrated irradiance monitoring and closed-loop control: Optional calibrated UV sensors enable automatic lamp power modulation to maintain setpoint irradiance at 340 nm, 420 nm, or broadband 300–400 nm—mitigating drift due to lamp aging or filter degradation.

Sample Compatibility & Compliance

The B-SUN chamber supports flat, rigid, and low-profile specimens up to 25 mm in height and 150 mm × 150 mm in footprint. Its modular tray system accepts industry-standard holders—including ASTM G155 specimen racks, ISO 105-B02 textile frames, and custom 3D-printed fixtures for irregular geometries. All models are designed and validated to meet regulatory requirements for method traceability and data integrity: irradiance calibration is NIST-traceable via YIHENG’s proprietary handheld irradiance calibrator (model IC-340), supporting ISO/IEC 17025-compliant lab accreditation. The controller firmware includes preloaded test profiles aligned with key standards—including GB/T 1865–2009 (coatings), SAE J2527 (automotive interiors), ISO 4892-2 (plastics), AATCC TM169 (textiles), and ASTM D6551 (roofing membranes)—and allows user-defined 10-segment ramp-hold programs with timestamped logging.

Software & Data Management

Data acquisition and reporting comply with GLP/GMP principles. The embedded controller logs all operational parameters—including irradiance (W/m²), black panel temperature (°C), chamber humidity (%RH), spray duration (min), and cumulative lamp hours—at configurable intervals (1 s to 60 min). Exportable CSV files include audit trails with operator ID, event timestamps, and system status flags. Optional Ethernet/RS485 interface enables integration into LIMS or centralized lab monitoring platforms. Firmware supports 21 CFR Part 11-compliant electronic signatures when paired with external authentication modules (not included). All calibration events—including sensor zeroing, irradiance verification, and lamp replacement—are automatically recorded with metadata and retained for ≥12 months.

Applications

The B-SUN series is routinely deployed in quality assurance and materials science laboratories for: accelerated color fading and gloss loss assessment of automotive clearcoats; UV-induced embrittlement testing of polyolefin films; lightfastness validation of inkjet-printed textiles per ISO 105-B02; durability screening of OLED encapsulation layers; and photochemical stability evaluation of pharmaceutical packaging under ICH Q1B conditions. Its spectral accuracy and irradiance stability make it suitable for comparative studies between material batches, supplier qualification, and failure root-cause analysis following field return investigations.

FAQ

What irradiance wavelengths can be monitored and controlled?
The system supports selectable irradiance control at 340 nm (for UV-driven degradation), 420 nm (for visible-light effects), or broadband 300–400 nm—each requiring a dedicated, factory-calibrated sensor.
Is the controller compliant with FDA 21 CFR Part 11?
The base controller meets ALCOA+ data integrity principles; full Part 11 compliance (including electronic signatures and audit trail encryption) requires optional authentication hardware and configuration by a qualified IT validation specialist.
Can the chamber operate without an irradiance sensor?
Yes—but irradiance will be open-loop (fixed lamp power only); closed-loop irradiance control and automatic lamp compensation require the optional sensor module.
What is the maximum sample thickness supported on the sliding tray?
The fully extended tray accommodates specimens up to 25 mm in vertical profile while maintaining uniform irradiance distribution.
Does YIHENG provide calibration certificates traceable to national standards?
Yes—each irradiance sensor ships with a certificate traceable to CNAS-accredited metrology institutes; on-site calibration services are available globally through authorized partners.
